SECURING DEVICE FOR JAR-COVERS OR THE LIKE.

' SPECIFICATION forming part of Letters Patent No. 729,908, dated June 2, 1903.

A li ation fil d January 2, 1903. Serial No.13 7,412. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. TATUM, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Securing Devices for Jar-Covers or the Like, of which the following is a specification.

My invention relates to devices used for securing the covers of preserve-jars, so as to produce an air-tight joint.

The object of my invention is to provide an exceedingly simple and cheap while at the same time effective device ofthe above-indt cated class. b

The invention will be fully described hereinafter, and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 is asectional elevation on line 1 1 of Fig. 2, and Fig. 2 is a plan with parts broken away. i

A indicates the body of the jar; B, the cover; 0, a yoke provided with hooks 1), arranged to take under a flange A of the jar; E, the securing device proper, and F a rubber washer interposed between the cover and the top of the jar. The detail construction of the jar and of that portion of the cover which fits the jar forms no part of my invention. The yoke O is, according to my invention, formed at its center with a downwardly-projected sleeve G, the upper end of which is coveredby the body of the yoke, said sleeve. being screw-threaded internally. Into this sleeve is arranged to project a screw-stem II, which extends upwardly from the disk E of the securing device proper. This disk is preferably milled or corrugated upon its periphery, so as to facilitate its manipulation. In line with the upper stem 11 there is arranged be;

low the disk E another stem, I, which is adapted to engage the top of the cover B, said top being preferably provided with a central depression or socket B to receive said stem.

The operation of my improved securing device will be obvious. By turning the disk E so as to cause the stem I to workdownward the cover B is pressed toward the jar, so as to produce an air-tight joint byuneans of the -washer'F. By turning the disk in the opposite direction the cover may be released.

The advantages of my improved securing device are that it is very simple and cheap,that there is no projection above the yoke O, that the upper surface of said yoke may be made perfectly smooth, that the member or element which engages the screw-thread is made rigid or integral with the member which engages the jar-cover, and that the pressure is applied exactly in the center of-the jar-cover, especially when the latter is provided with the depression or socket B.

I claim as my invention 1. In combination with a jar and a cover therefor having a central depression, a yoke adapted for locking engagement with the jar and having a smooth imperforate upper surface and an internally-threaded socket or sleeve projected downwardly from its lower surface, said socket being closed at its upper end, a disk arranged between said socket and the jar-cover, a screw-threaded stem projected from the disk upwardly into the said socket, and a pressure-exerting stem extending' downwardly from said disk in alinement with saidscrew-threaded stem and arranged to engage the jar-cover at the central depres sion thereof.

member and arranged to engage the jarcover. I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES A. TATUM.
